Systems and methods for improved identification and analysis of threats to a computing system

ABSTRACT

A security tool can access a tagging tool and the history generated by the tagging tool in order to identify potential threats and analyze the identified threats. When a potential threat is detected or an actual threat is identified, the security tool can request the history of actions from the tagging tool corresponding to the threat. The security tool can compare the potential or actual threat with the history of any action recorded by the tagging tool in order to classify a potential threat as an actual threat or determine the source or cause of an actual threat.

FIELD

This invention relates generally to computer software installation, configuration management, and security for a computing system.

DESCRIPTION OF THE RELATED ART

Today, a person using a computing system has a variety of avenues for obtaining software and installing the software on the computing system, such as purchasing physical media and downloading the software over a network. When downloading the software over a network, the person can acquire and install the software using a software package management system. The software package management system typically consists of a software repository which stores and maintains various software packages. The software packages typically consist of software stored in an archive format that includes data for installing the software.

To obtain the software package, the person can utilize a package manager. The package manager is responsible for retrieving the software package and installing the software package on the computing system. Typically, the package manager maintains a record of how the software package was installed. For example, the package manager may maintain data used to install the software package. However, the package manager does not maintain an accurate and complete history of why the software package was installed and the effect the installation had on the computing system. For example, if a user installs a software package, which causes the package manager to install software X and update software library Y, the user has no mechanism, at a later time, to determine why software library Y, was updated. Moreover, if library Y is later altered, the user has no mechanism to identify that the alteration of software library Y may affect software X.

In addition to the package manager, other software programs can alter the computing system. For example, the computing system can be under the control of a configuration management system. The configuration management system can be responsible for changing the configuration and settings of the computing systems. Likewise, the configuration management system can alter files on the computing system and install software on the computing systems. As with the package manager, the configuration management system does not maintain an accurate and complete history of why it has made changes to the computing systems. Additionally, the package manager and configuration management systems may not be aware of the changes that each makes.

In addition to software installation and configuration management, computer security is of paramount concern in a computing environment. Computer security typically includes identifying and preventing attacks on computing systems. In computer security, it can be difficult to distinguish between legitimate activity and malicious activity. Often, computer security applications and programs mistake legitimate activity, such as software installation and configuration management, with malicious activity.

DETAILED DESCRIPTION OF EMBODIMENTS

For simplicity and illustrative purposes, the principles of the present teachings are described by referring mainly to exemplary embodiments thereof. However, one of ordinary skill in the art would readily recognize that the same principles are equally applicable to, and can be implemented in, all types of information and systems, and that any such variations do not depart from the true spirit and scope of the present teachings. Moreover, in the following detailed description, references are made to the accompanying figures, which illustrate specific embodiments. Electrical, mechanical, logical and structural changes may be made to the embodiments without departing from the spirit and scope of the present teachings. The following detailed description is, therefore, not to be taken in a limiting sense and the scope of the present teachings is defined by the appended claims and their equivalents.

Embodiments of the present teachings relate to systems and methods for identifying and analyzing threats to a computing system. More particularly, a security tool can utilize a history of software package installations and configuration management actions in order to more effectively identify and analyze threats to a computing system.

According to embodiments, in order to track actions performed by a package manager and a configuration management system, a computing system can be configured to include a tagging tool. The tagging tool can be configured to cooperate with the package manager and the configuration management tool in order to determine and generate a history of the actions performed by the package manager and the configuration management system. The history can include a description of the actions, the reasons why the actions were performed, and a list and description of the software programs, files, and software libraries that are affected by the actions.

According to embodiments, a security tool can be configured to access the tagging tool and the history generated by the tagging tool in order to identify potential threats and analyze the identified threats. In particular, when a potential threat is detected or an actual threat is identified, the security tool can be configured to request, from the tagging tool, any actions in the history that may be associated with the threat. The security tool can be configured to compare the potential or actual threat with the history of any action recorded by the tagging tool in order to classify a potential threat as an actual threat or determine the source or cause of an actual threat.

By utilizing the tagging tool, the security tool can utilize a history of all actions performed by the package manager and the configuration management system when identifying and analyzing potential and actual threats to a computing system. Accordingly, the security tool can more efficiently and effectively eliminate legitimate activity as potential threats. Additionally, the security tool can more efficiently and effectively determine the source or cause of actual threats to the computing system.

FIG. 1 illustrates a software package delivery and management system 100, according to various embodiments of the present teachings. While FIG. 1 illustrates various components that can be included in the software package delivery and management system 100, one skilled in the art will realize that additional components can be added or existing components can be removed.

In embodiments, as illustrated in FIG. 1, the software package delivery and management system 100 can be designed to allow a computing system 102 to communicate with a software repository 104, via one or more networks 106, in order to obtain one or more software packages 108. The software repository 104 can be implemented as any type of open-source or proprietary software repository, which can store the software packages 108 and provide the software packages to computing systems, such as the computing system 102, requesting the software packages via the one or more networks 106. For example, the software repository 104 can be implemented as a Yellowdog Updater, Modified (Yum) repository, Debian™ repository, or any other type of conventional software repository.

In embodiments, as described herein, the software packages 108, can include one or more software programs that are packaged together in a format that allows a package manger or package installer to install the software programs, contained in the software packages 108, on a computing system. The software programs included in the software packages 108 can be any type of software programs such as operating systems (OS), application programs, and the like. The software packages 108 can also include metadata that describes the software package, such as the name of the software package, the software programs included in the package, version of the software package, description of the purpose of the software package, etc. The software packages 108 can also include metadata that aids in the installation of the software programs contained in the software packages 108, such as checksums and a list of dependencies of the software package. The list of dependencies can describe the relationship of the software programs contained in the software packages 108 and any other software programs, file, software libraries, etc. required by the software packages 108.

In embodiments, the software repository 104 can store the software packages 108 in any type of open-source or proprietary format depending on the type of software repository 104. For example, the software packages 108 can be in conventional formats such as RPM format for a Yum repository, .deb format for a Debian™ repository, or other conventional formats.

In embodiments, the software package delivery and management system 100 can also include one or more software repository mirrors 109, coupled to the network 106. The software repository mirrors 109 can be configured to maintain copies of the software packages 108. The software repository mirrors 109 can be configured to backup the software repository 104. For example, the software repository mirrors 109 can provide the software packages 108 to computing systems, such as computing system 102, in the event that the software repository 104 is unavailable or the software repository 104 is experiencing high traffic.

In embodiments, the software repository 104 and the software repository mirrors 109 can be supported by any type of computing system capable of storing the software packages 108, capable of communicating with the one or more networks 106, and capable of running a repository application for cooperating with a package manager or package installer in order to deliver the software packages 108. For example, the software repository 104 and the software repository mirrors 109 can be supported by conventional computing systems or other devices such as such as servers, personal computers, laptop computers, network-enabled media devices, networked stations, etc. As such, the computing system supporting the software repository 104 and the software repository mirrors 109 can include conventional hardware such as processors, memory, computer readable storage media and devices (CD, DVD, hard drive, portable storage memory, etc.), network devices, and the like.

In embodiments, the one or more networks 106 can be or include the Internet, or other public or private networks. The one or more or more networks 106 can be or include wired, wireless, optical, and other network connections. One skilled in the art will realize that the one or more networks 106 can be any type of network, utilizing any type of communication protocol, to connect computing systems.

In embodiments, the computing system 102 can be any type of conventional computing system or other device such as such as servers, personal computers, laptop computers, network-enabled media devices, networked stations, etc. As such, the computing system 102 can include conventional hardware such as processors, memory, computer readable storage media and devices (CD, DVD, hard drive, portable storage memory, etc.), network devices, and the like.

In embodiments, the computing system 102 can be configured to include a package manager 110. The package manager 110 can be configured to cooperate with the software repository 104 to perform various actions associated with the software packages 108. For example, the package manager 110 can be configured retrieve one or more of the software packages 108 and configured to install the software packages on the computing system 102. Likewise, the package manager 110 can be configured to retrieve updates to software packages 108, already installed on the computing system 102, and install the updates on the computing system 102.

In embodiments, the package manager 110 can be configured to cooperate with manager tools 112 to perform actions related to the software packages 108. For example, the manager tools 112 can be configured to install and update particular application programs, files, or software libraries maintained by the software repository 104. As such, the manager tool 112 can be configured to provide a request to the package manager 110 to perform the installation or update.

In embodiments, the package manager 110 can be configured to allow a user of the computing system 102 to request the various actions associated with the software repository 104 to be performed. To achieve this, the package manager 110 can be configured to provide command line or graphical user interfaces (GUIs) that allow the user to direct the package manager 110 to perform the actions. For example, the package manager 110 can provide GUIs that display the software packages 108, such as new software packages and software package updates, available in the software repository 104 and that allow the user to select the action to be performed related to the software packages 108.

In embodiments, in order to perform the various actions, the package manager 110 can be configured communicate with the software repository 104 and retrieve data from the software repository 104. For example, when providing the GUIs to a user of the computing system 102, the package manager 110 can retrieve a list of the software packages 108 from the software repository 104. Likewise, for example, when installing or updating a particular software package 108, the package manager 110 can retrieve the particular software package 108 and any other data associated with the particular software package 108.

In embodiments, when performing the various actions, the package manager 110 can be configured to utilize the metadata associated with the software packages 108 in order to perform the actions. For example, when installing a particular software package 108 or updating a particular software package 108, the package manager 110 can access the metadata associated with the particular software packages 108 in order to properly install or update the software packages on the computing system 102. For instance, the package manager 110 can utilize the list of dependencies in the metadata in order to identify the software programs, files, and software libraries that are affected. Additionally, when performing the various actions, the package manager 110 can be configured to store the metadata in a database 114.

In embodiments, the package manager 110 can be any application program that is capable of executing on the computing system 102 to perform the actions related to the software repository 104. For example, the package manager 110 can be any type of conventional open-source or proprietary package manager such as Yum package manager, Debian™ package manager, and the like. The package manager 110 can be stored on computer readable storage devices or media (CD, DVD, hard drive, portable storage memory, etc.) of the computing system 102 and executed by the computing system 102.

In embodiments, in order to track actions performed by the package manager 110, the computing system 102 can be configured to include a tagging tool 116. The tagging tool 116 can be configured to cooperate with the package manager 110 in order to determine and generate a history of the actions performed by the package manager 110. The history can include a description of the actions, the reasons why the actions were performed, and a list and description of the software programs, files, and software libraries that are affected by the actions. As such, the package manager 110 or a user of the computing system 102 can utilize the tagging tool 116 to track a history of all actions performed by the package manager 110 and the reasons the actions were performed. Additionally, the user of the computing system 102 and/or the package manager 110 can utilize the history of the action in order to access what effect additional actions will have on the computing system 102.

In embodiments, the tagging tool 116 can be configured to include an application programming interface (API) that the package manager 110 can call in order to invoke the tagging tool 116. For example, when the package manager 110 performs a particular action (software package 108 installation, software package 108 update, etc.), the package manager 110 can call the tagging tool 116. Once invoked, the tagging tool 116 can determine and generate the history of the particular action performed by the package manager tool 110 when called.

In embodiments, in order to determine the history, the tagging tool 116 can be configured to acquire the metadata and any other information associated with the action performed by the package manager 110. For example, when the package manager 110 invokes the tagging tool 116, the package manager 110 can be configured to provide, via the API, the metadata for the software package 108 associated with the action. Likewise, when the package manager 110 invokes the tagging tool 116, the package manager 110 can be configured to provide, via the API, other information such as a description of the action (e.g. action selected by the user via a GUI, description of the action, and the like). Additionally, the tagging tool 116 can be configured to retrieve, via the API, the metadata and any other information, associated with the action, from the database 114.

In embodiments, the tagging tool 116 can be configured to acquire, from a user of the computing system 102, additional information about the actions being performed by the package manager 110. To achieve this, the tagging tool 116 can be configured to generate GUIs that allow a user to enter information about the actions, such as comments on the actions, a description of the actions, etc. The tagging tool 116 can be configured to provide the GUIs and receive information entered into the GUIs via the API. For example, when the package manager 110 invokes the tagging tool 116, the tagging tool 116 can be configured to generate the GUIs and provide the GUIs, via the API.

In embodiments, once the metadata and any other information is acquired, the tagging tool 116 can be configured to identify specific information required to build the history of the actions performed by the package manager 110. The tagging tool 116 can be configured to parse the metadata and the other information associated with the action in order to extract any information that describes the action, the reasons the action was performed, and any software programs, files, and software libraries affected by the action. For example, the tagging tool 116 can parse and extract information such as the name of the software package 108, the version of the software package 108, the version of the previous software package 108 if updating, the reason the package manager 110 is performing the action (e.g. new software installation, software installation update), date and time of the action, and a list of software programs, files, and software libraries affected by the action.

In embodiments, once the information is identified, the tagging tool 116 can be configured to store the information in records reflecting the history of the actions performed by the package manager 110. The tagging tool 116 can be configured to store the information in a package event record 118 and a set 120 of change records 122. The tagging tool 116 can be configured to maintain the package event record 118 and the set 120 of change records 122 in a repository 124, such as a database.

In embodiments, the tagging tool 116 can be configured to utilize the package event record 118 to store the complete history of each action performed by the package manager 110. For each particular action, the tagging tool 116 can be configured to create an entry in the package event record 118. The tagging tool 116 can be configured to assign each entry in the package event record 118 a unique event identification. For each particular action, the tagging tool 116 can be configured to store in the entry, the unique event identification, any information that describes the particular action, the reasons the particular action was performed, the date and time, and any software programs, files, and software libraries affected by the particular action. As such, for each actions preformed by the package manager 110, the tagging tool 116 can maintain a complete history of the actions.

In embodiments, the tagging tool 116 can be configured to utilize the set 120 of change records 122 to store a history of how each action affects particular software programs, files, and software libraries. The tagging tool 116 can be configured to generate and maintain a separate change record 122 for each application program, file, or software library affected by an action of the package manager 110. Each time an entry is created in the package event record 118 for a particular action, the tagging tool 116 can be configured to create an entry in one or more change records 122 associated with the software programs, files, and software libraries affected by the particular action. For each entry, the tagging tool 116 can be configured to store, in each change record 122, the unique event identification, the effect of the action of the software programs, files or software libraries, a description of the action by the package manager 110, the date and time of the action, and the reasons for the action. As such, the tagging tool 116 can store a history of how each action effects particular software programs, files, and software libraries. Likewise, because the entries in the package event record 118 and the set 120 of the change records 122 share a unique event identification, the tagging tool 116 can identify and retrieve all the information associated with a particular action based on any information associated with the action.

In embodiments, the software package delivery and management system 100 can be configured to include a configuration management system 126, coupled to the network 106. The configuration management system 126 can be configured to perform various actions on the computing system 102. The action can include actions such as altering a configuration and settings of the computing system 102, installing and removing software packages on the computing system 102, installing and removing software programs on the computing system 102, modifying software programs, files, and software libraries on the computing system 102, and the like.

In embodiments, the configuration management system 126 can perform the actions in order to maintain consistency and reliability of the software package delivery system and management system 100. The actions can include tracking the types and configurations of the computing system 102. Additionally, the actions can include managing, setting, and altering the configurations of the computing system 102 utilizing management classes. A management class can include a description of rules, profiles, data, files, or configurations that can be applied to the computing system 102.

In embodiments, the configuration management system 126 can be configured to cooperate with a configuration management client 128 on the computing system 102. The configuration management client 128 can be configured to cooperate with the configuration management system 126 to perform the actions mentioned above. The configuration management client 128 can be implemented as an application program that is capable of executing on the computing system 102 to perform the processes as described above. In either case, the configuration management client 128 can be stored on computer readable storage devices or media (CD, DVD, hard drive, portable storage memory, etc.) of the computing system 102 and executed by the computing system 102.

In embodiments, the configuration management system 126 and the configuration management tool 128 can be configured as any type of open-source or proprietary configuration management system, protocol and/or tool, and configured to support any type of configuration management services, protocols, or methods. For example, the configuration management system 126 and the configuration management tool 128 can be implemented utilizing known configuration management systems and tools such as Puppet™, cfengine, bcfg2, chef, capistrano, fabric, spine, or any other type of proprietary or open-source systems or tools.

In embodiments, the tagging tool 116 can be configured to cooperate with the configuration management system 126 and the configuration management tool 128 in order to determine and generate a history of the actions performed by the configuration management system 126. The history can include a description of the actions, the reasons why the actions were performed, and a list and description of the software programs, files, and software libraries that are affected by the actions. As such, the configuration management system 126, the configuration management tool 128 or a user of the computing system 102 can utilize the tagging tool 116 to track a history of all actions performed by the configuration management system 126 and the reasons the actions were performed. Additionally, the user of the computing system 102, the configuration management system 126, and/or the configuration management tool 128 can utilize the history of the action in order to access what effect additional actions will have on the computing system 102.

In embodiments, the configuration management system 126 and/or the configuration management tool 128 performs a particular action, the configuration management system 126 and/or the configuration management tool 128 can call the tagging tool 116, via the API. Once invoked, the tagging tool 116 can determine and generate the history of the particular action performed by the configuration management system 126 and/or the configuration management tool 128 when called.

In embodiments, in order to determine the history, the tagging tool 116 can be configured to acquire any information associated with the action performed by the configuration management system 126 and/or configuration management tool 128. For example, when the configuration management system 126 and/or the configuration management tool 128 invokes the tagging tool 116, the configuration management system 126 and/or the configuration management tool 128 can be configured to provide, via the API, the details of the action taken. The information can include information that describes the action, the reasons the action was performed, and any software programs, files, and software libraries affected by the action. For example, the information can include the type of management action taken, the management classes used, the reasons for the action, the date of the action, identification of the software programs, files, and software libraries affected by the action, and details of the actions effect on the software programs, files, and software libraries.

In embodiments, the tagging tool 116 can be configured to acquire, from a user of the computing system 102 or the configuration management system 126, additional information about the actions being performed by the configuration management system 126 and/or the configuration management tool 128. To achieve this, the tagging tool 116 can be configured to generate GUIs that allow a user to enter information about the actions, such as comments on the actions, a description of the actions, reason for the action, etc. The tagging tool 116 can be configured to provide the GUIs and receive information entered into the GUIs via the API. For example, when the configuration management system 126 and/or the configuration management tool 128 invokes the tagging tool 116, the tagging tool 116 can be configured to generate the GUIs and provide the GUIs, via the API.

In embodiments, once the information is identified, the tagging tool 116 can be configured to store the information in records reflecting the history of the actions performed by the configuration management system 126 and/or the configuration management tool 128. The tagging tool 116 can be configured to store the information in a configuration event record 130 and the set 120 of change records 122. The tagging tool 116 can be configured to maintain the configuration event record 130 in the repository 124.

In embodiments, the tagging tool 116 can be configured to utilize the configuration event record 130 to store the complete history of each action performed by the configuration management system 126 and/or the configuration management tool 128. For each particular action, the tagging tool 116 can be configured to create an entry in the configuration event record 130. The tagging tool 116 can be configured to assign each entry in the configuration event record 130 a unique event identification. For each particular action, the tagging tool 116 can be configured to store in the entry, the unique event identification, any information that describes the particular action, the reasons the particular action was performed, the date and time, and any software programs, files, and software libraries affected by the particular action. As such, for each action preformed by the configuration management system 126 and/or the configuration management tool 128, the tagging tool 116 can maintain a complete history of the actions.

In embodiments, for each of the actions preformed by the configuration management system 126 and/or the configuration management tool 128, the tagging tool 116 can be configured to create an entry in the change record 122 associated with the software programs, files and software libraries affected by the action. For each entry, the tagging tool 116 can be configured to store, in each change record 122, the unique event identification, the effect of the action of the software programs, files or software libraries, a description of the action preformed by the configuration management system 126 and/or the configuration management tool 128, the date and time of the action, and the reasons for the action.

In embodiments, the action performed by the configuration management system 126 and/or the configuration management tool 128 can include an action to be performed by the package manager 110. As such, the tagging tool 116 can be configured to create an entry in the package event record 118. The entry can include the unique event identification of the action of the configuration management system 126 and/or the configuration management tool 128, the details of the action performed by the package manager 110 as described, and the reasons (e.g. at the direction of the configuration management system 126 and/or the configuration management tool 128).

In embodiments, to provide the history, the tagging tool 116 maintains the same unique event identification for a single action across the package event record 118, the configuration event record 130, and the set 120 of the change records 122. As such, the tagging tool 116 can store a history of how each action effects particular software programs, files, and software libraries. Likewise, because the entries in the package event record 118, the configuration event record 130, and the set 120 of the change records 122 share a unique event identification, the tagging tool 116 can identify and retrieve all the information associated with a particular action based on any information associated with the action.

In embodiments, the tagging tool 116 can be configured to retrieve the information stored in the package event record 118, the configuration event record 130, and the set 120 of change records 122, and organize and output the retrieved information in one or more reports. For example, the tagging tool 116 can be configured to receive requests, from the package manager 110, the configuration management system 126, the configuration management tool 128 and/or the user of the computing system 102, to view information on a particular action, a particular software package 108, and/or software programs, files, and software libraries. The tagging tool 116 can be configured to receive the request and generate one or more reports based on the request. The tagging tool 116 can be configured to provide the reports in GUIs, via the API. Likewise, the tagging tool 116 can be configured to generate and provide GUIs, via the API, that allows the user of the computing system 102 to request the reports and specify the subject of the reports.

In embodiments, the tagging tool 116 can be implemented as an application program that is capable of executing on the computing system 102 to perform the processes as described above. Likewise, the tagging tool 116 can be implemented as a portion of the package manager 110. In either case, the tagging tool 116 can be stored on computer readable storage devices or media (CD, DVD, hard drive, portable storage memory, etc.) of the computing system 102 and executed by the computing system 102. Likewise, the repository 124 can be stored on a computer readable storage devices or media (CD, DVD, hard drive, portable storage memory, etc.) of the computing system 102.

FIG. 2 shows an exemplary and generalized diagram of the tagging tool 116, according to various embodiments. As illustrated in FIG. 2, the tagging tool 116 can be configured to include various components, such as an API 205, records module 210, search module 215, repository interface 220, and reports module 225. It should be readily apparent to those of ordinary skill in the art that the tagging tool 116 depicted in FIG. 2 represents a generalized schematic illustration and that other components may be added or existing components can be removed or modified.

In embodiments, the API 205 can be configured to communicate with the package manager 110, the configuration management system 126 and/or the configuration management tool 128. In particular, the package manager 110, the configuration management system 126 and/or the configuration management tool 128 can utilize the API 205 to call and invoke the tagging tool 116 when an action is taken by the package manager 110, the configuration management system 126 and/or the configuration management tool 128. Likewise, the API 205 can be configured to communicate with the package manager 110, the configuration management system 126 and/or the configuration management tool 128 in order to receive or to retrieve information associated with the actions taken by the package manager 110, the configuration management system 126 and/or the configuration management tool 128. Once information is received, the API 205 can pass the information to the appropriate component such as records module 210 and reports module 225, which are coupled to the API 205.

In embodiments, the API 205 can also be configured to generate and provide various GUIs 230 associated with the tagging tool 116. For example, the API 205 can be configured generate and provide GUIs 230 that allow the user of the computing system 102 to request the reports and specify the subject of the reports. The API 205 can pass the information to the appropriate component such as records module 210 and reports module 225. Likewise, the API 205 can be configured to provide the reports via the GUIs 230, for example, reports generated by the reports module 225. Additionally, the API 205 can be configured to generate and provide GUIs that allow the user to enter information about the action of the package manager 110. The API 205 can be configured to generate the GUIs 230 in any format that can be presented, by the computing system 102, to the user, for example displayed to the user.

In embodiments, the records module 210 can be configured to receive the metadata and any other information which is acquired by the API 205. The records module 210 can be configured to identify specific information required to build the history of the actions performed by the package manager 110, the configuration management system 126 and/or the configuration management tool 128. The records module 210 can be configured to parse the metadata and the other information associated with the action in order to identify and extract any information that describes the actions, the reasons the action was performed, and any software programs, files, and software libraries affected by the action.

For example, for action by the package manager 110, the records module 210 can parse and extract information such as the name of the software package 108, the version of the software package 108, the version of the previous software package 108 if updating, the reason the package manager 110 is performing the action (e.g. new software installation, software installation update), the date and time of the action, and a list of software programs, files, and software libraries affected by the action. Likewise, for example, for action by the configuration management system 126 and/or the configuration management tool 128, the records module 210 can parse and extract information such as information that describes the particular action, the reasons the particular action was performed, the date and time, and any software programs, files, and software libraries affected by the particular action.

In embodiments, the records module 210 can be coupled to the search module 215 and the repository interface 220. Once the information is identified, the records module 210 can be configured store the information in records reflecting the history of the actions performed by the package manager 110, the configuration management system 126 and/or the configuration management tool 128. The records module 210 can be configured to store the information in the package event record 118, the configuration event record 130, and the set 120 of change records 122.

In embodiments, the records module 210 can be configured to utilize the package event record 118 to store the complete history of each action performed by the package manager 110. For each particular action, the records module 210 can be configured to create an entry in the package event record 118. The records module 210 can be configured to assign each entry in the package event record 118 a unique event identification. For each particular action, the records module 210 can be configured to store in an entry, the unique event identification, any information that describes the particular action, the reasons the particular action was performed, and any software programs, files, and software libraries affected by the particular action.

In embodiments, the records module 210 can be configured to utilize the configuration event record 130 to store the complete history of each action performed by the configuration management system 126 and/or the configuration management tool 128. For each particular action, the records module 210 can be configured to create an entry in the configuration event record 130. The records module 210 can be configured to assign each entry in the configuration event record 130 a unique event identification. For each particular action, the records module 210 can be configured to store in an entry, the unique event identification, any information that describes the particular action, the reasons the particular action was performed, and any software programs, files, and software libraries affected by the particular action.

In embodiments, the records module 210 can be configured to utilize the set 120 of change records 122 to store a history of how each action effects particular software programs, files, and software libraries. The records module 210 can be configured to generate and maintain a separate change record 122 for each software program, file, or software library affected by an action of the package manager 110, the configuration management system 126 and/or the configuration management tool 128. Each time an entry is created in the package event record 118 for a particular action, the tagging tool 116 can be configured to create an entry in one or more change records 122 associated with the software programs, files, and software libraries affected by the particular action. For each entry, the records module 210 can be configured to store, in each change record 122, the unique event identification, the effect of the action of the software programs, files or software libraries, a description of the action by the package manager 110, the date and time of the action, and the reasons for the action.

In embodiments, to create a new entry and store data in the package event record 118, the configuration event record 130, and change records 122 for software programs, files, and software libraries affected by an event, the records module 210 can be configured to cooperate with the search module 215 and the repository interface 220 to identify if the records exist. In particular, the records module 210 can pass a request to the search module 215 that identifies the package event record 118, the configuration event record 130, and change records 122 sought. The search module 215 can be configured to search the repository for the package event record 118, the configuration event record 130, and change records 122 sought via the repository interface 220. If the records exist, the search module 215 can be configured to retrieve the package event record 118, the configuration event record 130, and change records 122 sought, via the repository interface 220, and configured to pass the package event record 118, the configuration records 130, and change records 122 sought to the records module 210. If one or more of the records do not exist, the search module 215 can be configured to notify the records module 210, and the records module 210 can be configured to create the non-existent records. Once entries are made, the records module 210 can be configured to store the records in the repository 124, via the repository interface 220.

In embodiments, the reports module 225 can be coupled to the search module 215. The reports module 225 can be configured to receive a request for information stored in the repository and generate reports. In particular, the reports module 225 can be configured to cooperate with the search module 215 to identify the package event record 118, configuration records 130 and change records 122, which contain information relevant to the request. The search module 215 can be configured to search the repository, via the repository interface 220, and retrieve the package event record 118, the configuration event record 130, and any change records 122 relevant to the request. The search module 215 can pass the retrieved records to the reports module 225. As such, the reports module 225 can generate reports and pass the reports to the API 205 to provide in the GUIs 230.

As mentioned above, the tagging module 116 can track and record the history of actions performed by the package manager 110. For example, the package manager 110 can receive a request from a user of the computing system 102 to update a particular software package 108, such as updating Open Office from version 1 (v. 1) to version (v. 2). When the package manager 110 takes the action, the package manager 110 can call the tagging tool 116 via the API 205. Then, the package manager 110 can provide the tagging tool 116 with the metadata for the Open Office v. 2 and any other information relevant to the action.

In this example, the API 205 can pass the metadata for the open office v. 2 and any other information relevant to the action to the records module 210. The records module 210 can parse the metadata for the open office v. 2 and any other information relevant to the action and extract information describing the action and reason for the action such as the name of the software package 108 (Open Office), the version of the software package 108 (Open Office v. 2), the version of the previous software package 108 (Open Office v. 1), the reason the package manager 110 is performing the action (updating Open Office v. 1 to v. 2), the date and time (Jan. 1, 2009, 9:17 A.M.), and a list of software programs, files, and software libraries affected by the action (e.g. Open Office writer, Open Office spreadsheet, software library X, software library Y).

In this example, after extracting the information, the records module 210 can cooperate with the search module 215 and the repository interface 220 in order to retrieve the package event record 118 and the change records 122 for software programs, files, and software libraries affected by the action, such as the change records 122 for Open Office writer, Open Office spreadsheet, software library X, software library Y. The records module 210 can add a new entry in the package event record 118 and the change records 122 for Open Office writer, Open Office spreadsheet, software library X, software library Y.

FIG. 3A illustrates an exemplary diagram for adding a new entry 300 for the update of Open Office in the package event record 118 for the example described above. As illustrated, the package event record 118 can include previous entries such as entry 305, which details the installation of Open Office and is assigned a unique event identification 310, such as “00001”. The entry 305 can include such information as the name of the software package, the reason for the action, software programs, files, and software libraries affected by the action, the date and time of the action, and comments supplied by the user.

In this example, the records module 210 can create the new entry 300 and assign the new entry 300 a unique event identification 315, such as “00002”. The records module 210 can then populate the new entry with the information detailing the action, such as the name of the software package, the reason for the action, software programs, files, and software libraries affected by the action, the date and time of the action, and comments supplied by the user.

FIG. 3B illustrates an exemplary diagram for adding a new entry 350 for the update of Open Office in the change record 122 for the software library X, for the example described above. As illustrated, the change record 122 can include previous entries such as entry 355, which details the installation of Open Office and the addition of the software library X. The entry 355 can include such information as the unique event identification 310 “00001”, the actions effect on library X (“addition”), version of library X (“v. 1”), the reasons for the action (“Open Office v. 1 installed”), and date and time (“Nov. 3, 2008, 2:42 P.M.”).

In this example, the records module 210 can create the new entry 350 in order to detail the actions effect on library X. The records module 210 can populate the new entry 350 with the information of the action such as the unique event identification “00002”, the actions effect on library X (“updated”), version of library X (“v. 2”) the reasons for the action (“Open Office v. 1 updated to Open Office v. 2 installed”), and date (“Jan. 1, 2009, 9:17 A.M.”).

Continuing this example, the tagging module 116 can track and record the history of actions performed by the configuration management system 126 and/or the configuration management tool 128. For example, the configuration management system 126 and/or the configuration management tool 128 can initiate performing an action on the computing system 102, for instance, upgrading the operating system due to a change in the management class associated with the computing system 102. In this example, upgrading the operating system can cause the software library X to be upgraded to version 3 (v. 3). When the configuration management system 126 and/or the configuration management tool 128 takes the action, the configuration management system 126 and/or the configuration management tool 128 can call the tagging tool 116 via the API 205. Then, the configuration management system 126 and/or the configuration management tool 128 can provide the tagging tool 116 with the information related to the action such as a description of the action (upgrading the operating system), the reasons (a change in the management class), and the software programs, files, and software libraries affected by the action (software library X), and the details of the effect (software library X upgraded to v. 3).

In this example, the API 205 can pass the information relevant to the action to the records module 210. The records module 210 can parse the information and extract information describing the action and reason for the action such as the information related to the action such as a description of the action (upgrading the operating system), the reasons (a change in the management class), and the software programs, files, and software libraries affected by the action (software library X), and the details of the effect (software library X upgraded to v. 3).

In this example, after extracting the information, the records module 210 can cooperate with the search module 215 and the repository interface 220 in order to retrieve the configuration event record 130 and the change records 122 for software programs, files, and software libraries affected by the action, such as the change records 122 for software library X. The records module 210 can add a new entry in the configuration event record 130 and the change records 122 for software library X.

FIG. 4A illustrates an exemplary diagram for adding a new entry 400 for the update of the operating system by the configuration management system 126 and/or the configuration management tool 128 in the configuration event record 130 for the example described above. As illustrated, the configuration event record 130 can include previous entries such as entry 405 with a unique event identification 410 “10000”, which details the addition of a new management class. The entry 405 can include such information as the action performed, the reason for the action, software programs, files, and software libraries affected by the action, the date and time of the action, and comments supplied by the user.

In this example, the records module 210 can create the new entry 400 and assign the new entry 400 a unique event identification 415, such as “10001”, which details the update of the management class. The records module 210 can then populate the new entry with the information detailing the action, such information as the action performed, the reason for the action, software programs, files, and software libraries affected by the action, the date and time of the action, and comments supplied by the user.

FIG. 4B illustrates an exemplary diagram for adding a new entry 450 for the update of the operating system by the configuration management system 126 and/or the configuration management tool 128 in the change record 122 for the software library X, for the example described above. As illustrated, the change record 122 can include previous entries such as entry 355, which details the addition and upgrade of the software library X due to Open Office.

In this example, the records module 210 can create the new entry 450 in order to detail the actions effect on library X. The records module 210 can populate the new entry 450 with the information of the action such as the unique event identification “10001”, the actions effect on library X (“updated”), version of library X (“v. 3”) the reasons for the action (“update of management class A”), and date and time (“Feb. 1, 2009, 4:51 A.M.”).

As described above, the tagging tool 116 can be configured to generate a history of the actions performed related to software package installation and updates as well as configuration management. In embodiments, the tagging tool 116 can be configured to cooperate with other applications, programs, and tools of the computing system 102. The tagging tool 116 and the history generated by the tagging tool 116 can be utilized by the applications, programs, and tools of the computing system 102 to improve the performance of the computing system 102.

FIG. 5 illustrates another exemplary diagram of the software package delivery and management system 100 including the computing system 102 in which a security tool 502 can cooperate with the tagging tool 116 in order to identify and analyze threats to the computing system 102, according to various embodiments. While FIG. 5 illustrates various components that can be included in the software package delivery and management system 100, one skilled in the art will realize that additional components can be added or existing components can be removed.

In embodiments, the security tool 502 can be configured to identify and prevent security threats to the computing system 102. In particular, the security tool 502 can be configured to identify potential threats to the computing system 102 and classify the potential threats as actual threats. Likewise, the security tool 502 can be configured to analyze the identified threats in order to determine the cause or source of the identified threats. The threats can be any activity that could possibly harm the computing system 102, such as access to malicious network addresses or web sites, activity by malicious programs (Trojans, viruses etc.), attacks by malicious agents (hacking, spamming, phishing etc.), and the like.

In embodiments, in order to identify the threats, the security tool 502 can be configured to monitor the resources of the computing system 102. In particular, the security tool 502 can be configured to monitor the file system of the computer readable storage media of the computing system 102, for instance, monitor for attempted access to privileged or restricted files, directories, programs, etc. Likewise, the security tool 502 can be configured to monitor the network resources of the computing system 102, for instance, monitor for attempted access to or communication from restricted network ports, attempted access to restricted network addresses or web sites, abnormal log-in behavior of the users of the computer system 102, and the like.

In embodiments, the security tool 502 can be configured to maintain a security record 504. The security record 504 can be configured to store lists of privileged or restricted files, directories, programs, etc., restricted network ports, restricted network addresses or web sites, access information for the users of the computing system 102, known malicious agents, and the like. As the security tool 502 monitors the resources of the computing system 102, the security tool 502 can be configured to access the security record 504 in order to identify and analyze potential threats to the computing system 102.

In embodiments, the security tool 502 can be implemented as an application program that is capable of executing on the computing system 102 to perform the processes as described above. Likewise, the security tool 502 can be implemented as a portion of another application program of the computing system 102, such as the OS. In either case, the security tool 502 can be stored on computer readable storage devices or media (CD, DVD, hard drive, portable storage memory, etc.) of the computing system 102 and executed by the computing system 102.

In embodiments, the security tool 502 can be configured to access the tagging tool 116 and the history generated by the tagging tool 116 in order to identify potential threats and analyze the identified threats. In particular, when a potential threat is detected or an actual threat is identified, the security tool 502 can be configured to request, from the tagging tool 116, information from the package event record 118, the configuration event record 130, and any change records 122. The security tool 502 can be configured to compare the potential or actual threat with the history of any action recorded by the tagging tool 116 in order to classify a potential threat as an actual threat or determine the source or cause of an actual threat. To access the tagging tool 116, the security tool 502 can be configured to invoke the tagging tool 116 via the API, such as API 205 illustrated in FIG. 2, of the tagging tool 116 and configured to request information via the API.

In embodiments, the security tool 502 can be configured to request information from the tagging tool 116 based on any number of parameters associated with the potential or actual threat. For instance, the security tool 502 can be configured to request information from the package event record 118, the configuration event record 130, and any change records 122 based on the date and time of the potential or actual threat. Likewise, the security tool 502 can be configured to request information from the package event record 118, the configuration event record 130, and any change records 122 based on the computing resources (file, directory, network port, network address, etc.) associated with the potential or actual threat.

In embodiments, the security tool 502 can be configured to utilize the information provided by the tagging tool 116 to classify a potential threat as an actual threat. In particular, if the security tool 502 detects activity that can potentially be a threat, the security tool 502 can compare the information provided by the tagging tool 116 to determine if the detected activity corresponds to actions recorded by the tagging tool 116. As such, the security tool 502 can eliminate activity recorded by the tagging tool 116 as actual threats.

In embodiments, for example, the security tool 502 can designate software library X as a restricted file. In this example, the security tool 502 can detect a change to software library X on the date “Feb. 1, 2009” at the time “4:57 A.M.” Once detected, the security tool 502 can invoke the tagging tool 116 and request any information recorded for software library X on the date “Feb. 1, 2009”. In response, the tagging tool 116 can retrieve information from the entry 450 from the change record 122 of the software library X (e.g. a change occurred due to an update of management class A) and provide the information to the security tool 502. Accordingly, the security tool 502 can classify the detected change to software library X as not being an actual threat because it corresponds to an authorized action e.g. an update to the management class A.

In embodiments, the security tool 502 can be configured to utilize the information provided by the tagging tool 116 to determine the cause or source of an actual threat. In particular, if the security tool 502 detects activity and identifies the activity as a threat, the security tool 502 can compare the information provided by the tagging tool 116 to determine if the detected activity identified as an actual threat corresponds to actions recorded by the tagging tool 116. As such, the security tool 502 can identify the sources or causes of identified threats and mitigate the threats.

In embodiments, for example, the security tool 502 can detect an attempted access to a restricted network address from the security record 504 on the date “Nov. 3, 2008” at the time “3:00 P.M.”. Because the network address is restricted, the security tool 502 can identify the attempted access as an actual threat. Once detected, the security tool 502 can invoke the tagging tool 116 and request any information recorded for the date “Nov. 3, 2008”. In response, the tagging tool 116 can retrieve information from the entry 305 from the event record 118 (e.g. “Open Office v. 1” was installed at “2:42 P.M.”) and provide the information to the security tool 502. Accordingly, the security tool 502 can determine that the installation of “Open Office v. 1” or one of the files associated with “Open Office v. 1” can potentially be the source of the actual threat.

In embodiments, once the security tool 502 identifies an actual threat, the security tool 502 can be configured to take various actions. The security tool 502 can be configured to block or prevent the activity associated with the actual threat. Likewise, the security tool 502 can be configured to notify the user of the computing system 102 of the actual threat. In the notification, the security tool 502 can be configured to provide the information received from the tagging tool 116 to the user of the computing system 102.

FIG. 6 illustrates an exemplary diagram of hardware and other resources that can be incorporated in the computing system 102 and configured to communicate with the software repository 104 and the configuration management system 126 via one or more networks 106, according to embodiments. In embodiments as shown, the computing system 102 can comprise a processor 602 communicating with memory 604, such as electronic random access memory, operating under control of or in conjunction with operating system 606. Operating system 606 can be, for example, a distribution of the Linux™ operating system, such as Red Hat™ Enterprise Linux, Fedora, etc., the Unix™ operating system, or other open-source or proprietary operating system or platform. Processor 602 also communicates with one or more computer readable storage devices or media 608, such as hard drives, optical storage, and the like, for maintaining the operating system 606, package manager 110, the configuration management client 128, the tagging tool 116, the security tool 502, and the repository 124. Processor 602 further communicates with network interface 610, such as an Ethernet or wireless data connection, which in turn communicates with one or more networks 106, such as the Internet or other public or private networks.

Processor 602 also communicates with the package manager 110, the configuration management client 128, the tagging tool 116, and the security tool 502 to execute control logic and allow performance of the security and threat detection processes as described above and below. Other configurations of the computing system 102, associated network connections, and other hardware and software resources are possible.

While FIG. 6 illustrates the computing system 102 as a standalone system including a combination of hardware and software, the computing system 102 can include multiple systems operating in cooperation. The security tool 502 can be implemented as a software application or program capable of being executed by the computing system 102, as illustrated, or other conventional computer platforms. Likewise, the security tool 502 can also be implemented as a software module or program module capable of being incorporated in other software applications and programs, such as the operating system of the computing system 102 or the tagging tool 116. In any example, the security tool 502 can be implemented in any type of conventional proprietary or open-source computer language. When implemented as a software application or program code, the security tool 502 can be stored in a computer readable storage medium, such as storage 608, accessible by the computing system 102. Likewise, during execution, a copy of the security tool 502 can be stored in the memory 604.

FIG. 7A illustrates a flow diagram for detecting and analyzing security threats, according to embodiments of the present teachings. In 702, the process can begin. In 704, the security module 502 can detect a potential threat to the computing system 102. The threats can be any activity that could possibly harm the computing system 102, such as access to malicious network addresses or web sites, activity by malicious programs (Trojans, viruses etc.), attacks by malicious agents (hacking, spamming, phishing etc.), and the like. In order to identify the threats, the security tool 502 can monitor the resources of the computing system 102. For example, the security tool 502 can monitor the file system of the computer readable storage media of the computing system 102, for instance, monitor for attempted access to privileged or restricted files, directories, programs, etc. Likewise, for example, the security tool 502 can monitor the network resources of the computing system 102, for instance, monitor for attempted access to or communication from restricted network ports, attempted access to restricted network addresses or web sites, abnormal log-in behavior of the users of the computer system 102, and the like.

In 706, the security module 502 can invoke the tagging tool 116 and request information corresponding to the potential threat. The security tool 502 can request information from the tagging tool 116 based on any number of parameters associated with the potential threat. For instance, the security tool 502 can request information from the package event record 118, the configuration event record 130, and any change records 122 based on the date and time of the potential threat. Likewise, the security tool 502 can request information from the package event record 118, the configuration event record 130, and any change records 122 based on the computing resources (file, directory, network port, network address, etc.) associated with the potential threat.

In 708, the security module 502 can receive the information from the tagging tool 116. In 710, the security module 502 can compare the information to the potential threat to determine if the potential threat is an actual threat. For example, if the tagging tool 116 provides information that corresponds to the potential threat, the security module 502 can eliminate the potential threat as an actual threat.

In 712, the process can end, but the process can return to any point and repeat.

FIG. 7B illustrates another flow diagram for detecting and analyzing security threats, according to embodiments of the present teachings. In 752, the process can begin. In 754, the security module 502 can detect an actual threat to the computing system 102. The threats can be any activity that could possibly harm the computing system 102, such as access to malicious network addresses or web sites, activity by malicious programs (Trojans, viruses etc.), attacks by malicious agents (hacking, spamming, phishing etc.), and the like. In order to identify the threats, the security tool 502 can monitor the resources of the computing system 102. For example, the security tool 502 can monitor the file system of the computer readable storage media of the computing system 102, for instance, monitor for attempted access to privileged or restricted files, directories, programs, etc. Likewise, for example, the security tool 502 can monitor the network resources of the computing system 102, for instance, monitor for attempted access to or communication from restricted network ports, attempted access to restricted network addresses or web sites, abnormal log-in behavior of the users of the computer system 102, and the like.

In 756, the security module 502 can invoke the tagging tool 116 and request information corresponding to the actual threat. The security tool 502 can request information from the tagging tool 116 based on any number of parameters associated with the actual threat. For instance, the security tool 502 can request information from the package event record 118, the configuration event record 130, and any change records 122 based on the date and time of the actual threat. Likewise, the security tool 502 can request information from the package event record 118, the configuration event record 130, and any change records 122 based on the computing resources (file, directory, network port, network address, etc.) associated with the actual threat.

In 758, the security module 502 can receive the information from the tagging tool 116. In 760, the security module 502 can compare the information to the actual threat to determine a cause or source of the actual threat. For example, if the tagging tool 116 provides information that corresponds to the actual threat, the security module 502 can classify the software package and/or configuration management action provided in the information as potentially the cause or source of the actual threat.

In 762, the process can end, but the process can return to any point and repeat.
